I have to wonder. Given that dual tower 140mm CPU heatsink fans like the D15 are rated for 300W, how does the fin area of the D15 compare to the 5090’s total fin area, which is supposed to dissipate 600W? The 4090’s fans were 116mm in diameter. I’m now curious how loud it will be…
Big chip, more surface area, less thermal density. I suspect it'll work at a decent noise level.

Are the tools failing at higher GHz?
Sometimes things just go kinda wrong.
Silicon process has gotten too expensive to simply throw more transistors at the problem. The only exception is for the price is no object 090 series buyers.
pretty unrefined cope.
A) New architecture: There is none that impacts gaming rasterization. Only the RT/AI side has any kind of significant update.
yeah that's the thing.
It's the same underlying design on the same process
It's not.
Significantly higher clocks weren't going to happen.
It's specifically a streamlined SM design (especially for SMSP schedulers and operand forwarding network parts of it), which, you know, it supposed to give you moar frequency.
Remember Maxwell? dat thing clocked a lot, lot more than Kepler ever did, all courtesy of the SM no longer being a horribly overbuilt turd.
and nothing else can have much impact on the exact same process with the same underlying gaming architecture.
what is RDNA4 then.
RDNA2 for that matter, too.

This is how Nvidia dies. It kind of feels like how Intel suddenly died. Everyone was so used to the idea of automatic improvements tied to shrinkage, that when Intel decided to stagnate the market with 4 faster cores vs 6 slower, more expensive cores, forcing gamers to make the impossible choice, that an entire generation of gamers were traumatized by that, and I'm glad intel is dead now, I feel better and they deserve their fate even now, more than the commas I gave them for free.

I don't think so.
  1. Nvidia retains performance per area
  2. Nvidia retains performance per watt
  3. Nvidia made a big die
  4. Next generation it has a new process to offer some improvements again
So it's not until 2029 or so that things may get very boring unless Radeon is back by then.

Except Nvidia is used to be on worse nodes than the competition, while for Intel it was the opposite until later, where they couldn't react.
So they are nothing alike.

Yes. Nvidia was on a worse mode with Samsung for 3000 series, and still outdid AMD. This is all intentional to make more money.

They could have put 5080 on a bigger die, to at least achieve 4090 performance, but this makes them more money. 5080 will still sellout, as it has no competition, and why get a 4080, when the 5080 is better for the same price.

The only alternative I’d see is getting a used 4090 over a 5080. But, they’ve held their price really well and it’s another price bracket. I sold my 4090 for the same $2400 I paid for it brand new.

I actually want an FE for once, I like the small design. So long as it’s quiet, I’ll try for the miracle to order one launch night from Best Buy.

I love that tiny main PCB of the FE. Be interesting to see what design Nvidia partners use.
I'm very interested to see some detailed looks into how well the cooling system works. If it cools this (nearly) 600w card hopefully it'll be used in future, more mainstream, cards.

Honestly the overall design of the FE 5090 really makes me want to buy it, but then I really don't want to encourage that kind of pricing!

Is the 5080 using the same flow through vapour chamber cooler? I've not had an Nvidia card in ages, I'm tempted tbh.
It hasn't been confirmed by disassembly but they look the same. And Nvidia did reuse the RTX 4090 cooler for the 4080 as well.
I don't know how it is in Wales but in the US availability of FE cards has been scarce.

If the RTX 5070 has worse performance per watt than the 7900 XTX in the TPU chart am I allowed to call it an RDNA3-tier flop?

It sounds like a big if...

If it's like the 4090 and 3090, the FE will be one of the hardest to find because it's Best Buy only. I like the FE design but it often costs as much on ebay/craigslist/etc. as the flagship cards with AIO loops, which are better if you're spending that much anyway.

Hopefully they'll use it on the rest of the line up for subsequent series (and AMD copies them) assuming that it works well!

Apparently Nvidia sells them through Scan in the UK.

My only question would be, with the three PCBs in the FE 5090, and the ribbon cables. Doesn’t that create more failure points? Idk,
Not an engineer. There is also the conductive Liquid Metal.

Still think FE is the way to go, looks really cool and will resell well when the time comes. They are just near impossible to get in Canada. You can only order them from best buy online, and there are no protections from bots. Hoping launch night there are enough to get an order in if the website doesn’t die.

After how cold it was this weekend I could use an 800W space heater. If it can play some computer games while I'm huddling under the blankets all the better.

Just be careful pairing it with an OC 14900k or you might exceed the limit of a standard NEMA 5-15 outlet and/or start tripping breakers if your monitor and some other stuff are on the same circuit.
